In this article, we investigate the structures of the pseudoscalar charmonium and bottomonium in the framework of the coupled rainbow SchwingerDyson equation and ladder Bethe-Salpeter equation with the confining effective potential (infrared modified flat bottom potential). As the current masses are very large, the dressing or renormalization for the c and b quarks are tender, however, mass pol...

The q ¯ q spectrum is studied in a generalized constituent quark model constrained in the study of the N N phenomenology and the baryon spectrum. An overall good fit to the available experimental data is obtained. A detailed analysis of all sectors from the light-pseudoscalar and vector mesons to bottomonium is performed paying special attention to the existence and nature of some non well-esta...

We have calculated the width of the rare decay H → γγZ at one-loop level in the standard model for Higgs boson masses in the range 115GeV ≤ mH ≤ 160GeV . For this range of Higgs boson masses we find that Z boson is predominantly longitudinally polarized, and the photons have the same helicity. A comparison of the decay width Γ(H → γγZ) to those of H → γγ and H → γZ shows that, for the Higgs bos...

We test the one-loop chiral perturbation theory formula on unquenched lattice data of pseudoscalar meson decay constants. The chiral extrapolation including the effect of the chiral logarithm is attempted and its uncertainty is discussed.
